M. B. HARRIS GAR HEATER Filed Oct. 7, 1925 Patented June 2, 1931 i f UNITEDr STATES PATENT OFFICE j MARK RHARRrs, oF BIRMINGHAM, MICHIGAN, AssrenoR To GENERAL MoToRs ooR-'n roRATIoN, or DETROIT, MICHIGAN, A ooRroR-ATron or DELAWARE CAR HEATER .Application filed October 7, 1925. SeriaLNo. 61,153.

The object of this invention is to provide a heater particularly designed for use upon automobiles, which will supply the interior of the vehicle with clean, fresh air, warmed '5 by Contact with a heated engine part such as the exhaust manifold of the engine. The construction is of such character that when it is not desired that it function as a heater, as in hot weather, it may be so adjusted as to divert the heated air away from the Ainterior of the car, or even, if desired, may be adjusted so as to actually serve to cool a portion of the engine, such as the intake manifold and thus prevent over-heating thereof.

From another point` of view my invention i My device is also marked by simplicity of construction and'A ease of assembly asv will appear from the detailed description which follows. Y j Y In the drawings: Figure 1 is a side elevation of an automobile engine with -m improved heater applied a0 thereto, portions o the car body being shown Vin section;y

l. In Figure l I have shown a portion of an Oakland automobile vto which my invention has been applied'. The reference character 2 indicates, generally, an enginehaving an 50,1ated for heatingthe incoming mixture in exhaust manifold 6 andan intake manifold `cold weather. In automobiles ofthis make a valve device, indicated at 10.in`Figure 5, is provided bymeans of which, if desired,

lthe exhaust vgases may be diverted from the manifolds and comprises an elongated strip of metal formed to provide a top portion 20, a side portion V22, and va bottom portion 24. The top portion 20 is preferably apertured as at 2l to permit access tothe valve device a cover plate shown at The portion 2O 10, the aperture being ordinarily closed byk of the casing is also vprovided with an L- shaped flange `26 to the horizontal leg of which is secured inany suitable manner a member 28. The overlying portions ofthe flangel 26 and member28 are apertured as shown at 30, Figure 5, to permit passage of the bolts 32 shown in Figure 4,l which serve to'clamp the cylinder head to the cylinder block andrto hold the heaterin position as well. lThe bottom portion of the vcasingis slotted as at 34 to permit passage of thepor- [tion ofthe. intake manifold which is connectedr to the carburetor. be clamped to the manifold adjacent/the The casing may opening 34 if desired. A The side portion 22 is secured tothe enf lgine by means of screw bolts36 which engage L-shaped clips 38 kwhich are prefer-ably held in position by the same bolts 40 which v secure the intake manifold to the enginekv bl'ock. l IThefront end of the casing 18 is closed by a cap 42 which may be welded 'to the main body of the casing. The' 'cap 42 is; provided with :a circular aperture 43`ha'ving a rotatable cover 44whichis ivoted at 45 to to be latery described. The'closure is'provided with a finger' tab 47 which is adapted to be engaged by either of two spring clips a bent-over extension'46 of t e partition 64 casing being provided at its rear end with air discharge ports, one of said ports being adapted to conduct air to a desired point, and controlling means for said ports.

8. The combination of an automobile engine provided with intake and exhaust manifolds and the usual cooling fan, a casing inclosing said manifolds and provided at its forward end with air admission means facing the fan blast, a partition in the oasing between the manifolds, and a valve c0- operating with said means and adjustable todirect air upon either Vside of said partition as desired, said casing being provided at its rear end with air discharge ports, one of said ports being adapted to conduct air4 to a desired point, and controlling meansfor said ports.

' 9. The combination of an engine having.l an intake manifold and an exhaust manifold, a casing for said manifolds, adjustablemeans for introducing air under pressureupon one side or the other of said casing to direct air upon the intake manifold or k upon the exhaust manifold as desired, and means for discharging air from the casing. 10. The combination of an automobile engine provided with intake and exhaust manifolds and the usual cooling fan, a easing inclosing said manifolds and provided at its forward end with air admission means facing the fan blast, adapted to admit air to said manifolds, and a valve lassociated with said means and adjustable to direct air upon v5 either of said manifolds as desired, said casing being'provided at its rear end with an air discharge port.
